Abstract

La présente invention concerne un dispositif modulaire modifiant la façon d'utiliser un vélo à dérailleur, sans modification de sa constitution d'origine. L'invention permet un passage automatique des braquets en fonction de la vitesse de pédalage. L'invention comprend trois sous-ensembles principaux, à savoir: 1) le Processeur Central (UC) chargé des décisions logiques, 2) le Moteur de Couple M1 (Ensemble M1) qui est l'ensemble actionneur auquel est couplé le codeur et auquel est fixé le câble de dérailleur, et 3) le Moteur M2 (Ensemble M2) qui set une dynamo de faible puissance servant de capteur de vitesse de pédalage et de chargeur de batterie. L'invention convient sensiblement à tous les modèles de vélos à dérailleurs dans la mesure où il fonctionne avec une logique de boucle ouverte. Comme preuve de sa souplesse d'utilisation, l'invention peut être programmée pour prendre en compte les pignons et plateaux déjà en place. On dispose de deux codeurs de position qui sont jumelés avec le moteur de couple M1 de façon à assurer une indexation précise aussi bien dextrogyre (Cw) que sénestrogyre (Ccw). L'invention permet certaines variations en fonction des dispositifs électromécaniques à utiliser. Comme codeur de l'ensemble M1 divers dispositifs conviennent dans la mesure où ils fournissent une rétroaction de position comme peut le faire un codeur à potentiomètre, à tête et piste magnétiques, optique ou linéaire. De même, le détecteur de vitesse de pédalage de l'ensemble M2 peut être réalisé à base de transistor à effet Hall, de dynamo ou moteur à courant continu ou de capteurs à infrarouge ou à induction.
